Notes:

The Dreaded 13th Spell (A.K.A The Curse of the Horned One) was one of the most powerful and hilarious spells on the original table top version of Warhammer Fantasy.

It took a massive amount of luck to pull off, but if you did it, you got to roll 4D6 (Four six-sided dice) and whatever number you got was the number of kills you inflicted on that particular unit. If the unit died as a result of this, you replace every single member with a Clanrat you control.

This also applied to special characters.

Grimgor and his mob of black orcs? Clanrats.

Teclis and his wizard council? Clanrats.

Archaon the Everchosen, Grand Marshal of Chaos Undivided, and his elite band of Chosen? Clanrats M----------!

And the best thing about all of this?

There are no saves.

There are no re-rolls.

There is only Clanrats.
